Re: Oral puzzles
Hi ganesh;
In mathematics, you don't understand things. You just get used to them.
90% of mathematicians do not understand 90% of currently published mathematics.
I am willing to wager that over 75% of the new words that appeared were nothing more than spelling errors that caught on.

Star members have too many stars. So, if I congratulate new star members, so, that means I need more stars for my picture?

Hi;
Yikes! I gave the 10th term instead of the sum!

Re: Oral puzzles
I think this is a right triangle.
So, I will compute:
180-90=90
Split:45
I don't know if tan P is 45
and cot R is 45, too.
